STEAM H EATING APPARATUS.

SPECIFICATION forming part of" Letters Patent No. 263,739, datedSeptember 5, 1882, Application filed J one 30, 1882. (No model.)Patented in Germany June 29, 1881, No. 17,309.

To all whom it may concern:

Be it known that I, EDUARD WERNER, of Grimma, inthe Kingdom of Saxony,German Empire, have invented an Improvement in Steam Heating Apparatus,of which the following is a specification. Letters Patent for thisinvention were granted to me in German Empire on June 29, 1881, No.17,309.

This invention relates to steam heating apparatus for dwellings andbuildings in which steam-generators of small capacity are used; and theobject of the invention is to provide for the automatic feed of water tothe boiler, in order that the apparatus shall be independent-of theattention of servants in this respect, and to provide for regulating thesteam-pressure without employing the ordinary weighted or springsafety-valves.

In the drawing the steam heating apparatus is shown by an elevation,partly in section.

A represents the boiler, which may be placed in the cellar or in anyconvenient part of the house. It may be connected with the stove orrange in the kitchen.

B is the feed-water tank, placed above this boiler, and the sizeof thistank must be proportionate to the size of A, and should be adapted tocontain water suflicieut for twentyfour hours working at least.

0 and d are pipes connecting A and B, the pipe 0 passing from the top ofB and into A to about the water-level, and d passing from the bottom ofA to the bottom of B. The end of the pipe 0 in A is provided with asmall cup, into which a short cylinder is inserted, and there is anopening between the lower part of the cylinder and cup, which permitsthe passage of steam and water to the pipe 0.

The operation of the parts thus far described is that, upon steam beinggenerated in A by the fire beneath it, water will be forced from A. intoB through the pipe d until the mouth of the'pipe c in A is free. Thensteam will pass by the pipe 0 into B, and water will run by gravity fromB into A through the pipe (I until the mouth of c in A is closed by therising water, and so on, and the boiler A is thereby constantly suppliedwith water. If there are but slight variations in the steampressure, thewater-level in A will be nearly constant on the line of the mouth of cin A.

f is a pipe for steam, extending from the upper part of the boiler A andpassing to the various radiators in the house or building.

I have shown three radiators, two, A B, represented as in an upperstory, and one, C, as located upon the same floor as the boiler.

" m are the return-pipes from A B for the water of condensation whichpasses to the tank B, and m the return-pipe-from O, which passes to thebox g, from which it may be forced through the pipe 1" into a smalltank, 9, by steam-pressure, and from p it passes to B by a pipe andcock.

g is a branch from the steam-pipef, and one end of 9 opens into a box,It, containing water. Extending upwardly from the box 70 are pipes h 'i,that end at the blow-off box 1. The

ends of the pipes h i in k are at different levels, and when thesteam-pressure in A becomes excessive the steam passing by the pipe 9will act upon the water in 7r and force it up into h and 6 until themouth Of'i in k is free. Then the steam will escape through i to l, andwill blow oft into the atmosphere and relieve the pressure in A. As soonas such steampressure is relieved the column of water in II, descends,raising the water-level in k and closing tlle'mouth of t, and thisoperation will be repeated whenever the steam-pressure exceeds themaximum point.

The maximum steam-pressure of the apparatus is determined by thedistance between the boxes is and l, and the consequent height insteadof passing to radiators for heating purposes, might pass to engines fordriving light machinery.

. I claim as my invention- The boiler A and tank B, connected by thepipes c and d, in combination with the steampipe f, return-pipe 121,boxes 70 l, and pipes g, h, i, and a, substantially as and for thepurposes specified.

This specification signed by me this 23d day of May, A. D. 1882.
